A football stadium on the West Side of Manhattan is most popular in New York’s suburban counties, where nearly half of the voters surveyed like the project, a new poll out yesterday found.

In the city, however, support for the $1.9 billion project slips to 41 percent, compared with 50 percent of Big Apple voters saying they oppose the stadium and 8 percent undecided, the Quinnipiac University poll found.

Meanwhile, a judge will hear charges today that the MTA shortchanged the riding public by failing to accept the highest bid for its railyards, which went to the Jets for $250 million.
